Abstract
Essential tremor (ET) is one of the most common movement disorders. Its clinical manifestations not only include typical kinetic and/or postural tremors, but also other non-motor symptoms such as cognitive dysfunction, sleep disturbance, and dysosmia. The exact etiology and pathogenesis of ET is still unknown. Approximately 60% of ET patients have a family history, and genetic factor plays an important role in the onset of the disease. Researchers have so far identified 3 genetic loci (ETM 1-3) through family studies, and proposed additional causative genes such as FUS, HTRA2, TENM4, NOS3 and susceptibility genes such as LINGO, SLC1A2, and GABA. This review focuses on the progress made in genetic research on ET.
